摘要： A scheduler stores data to be scheduled. The scheduler may include an array that identifies relative priorities among the queue entries according to a first priority scheme, such as by age. The scheduler also may include a priority register array identifying relative priorities among the queue entries according to a second priority scheme, such as by data type. A plurality of detectors coupled to the array and to the priority register array may determine which data is to be scheduled next.

摘要： An error correction system in an agent provides an error correction in a circuit path extending from an internal cache to an output of the agent. When data errors are detected for data to be processed internally within the agent, the error correction system passes the corrupted data through the error correction circuit, and out of the agent and back into the agent. The error correction changes internal data requests into an external transaction when data errors are detected.

摘要： A multi-mode transaction queue may operate according to a default priority scheme. When a congestion event is detected, the transaction queue may engage a second priority scheme.

摘要： Increased efficiency in a multiple agent system is provided by allowing all explicit writebacks to continue during a snoop phase. Upon each incoming external bus request, an agent determines if the address of that request matches an address of data within the agent. If there is a match, the agent copies this most recent data, changes the state of the data to unmodified, changes the length of the data to zero (for pending explicit writebacks), and performs an implicit writeback. Additionally, prior to each explicit writeback, an agent determines if the address of the explicit writeback and any incoming snoop request requests are the same. If there is a match, the agent changes the data length of the explicit writeback to zero prior to issuing the explicit writeback.

摘要： A processing agent is used in a system that transfers data of a predetermined data line length during external transactions. The agent may include an internal cache having a plurality of cache entries. Each cache entry may store multiple data line lengths of data. The agent further may include a transaction queue system having queue entries that include a primary entry including an address portion and status portion, the status portion provided for a first external transaction of the agent, and a secondary entry including a status portion provided for a second external transaction.

摘要翻译： 通过允许所有显式回写在窥探阶段继续进行，从而提高了多代理系统的效率。 在每个传入的外部总线请求时，代理确定该请求的地址是否匹配代理中的数据的地址。 如果有匹配，代理将复制最近的数据，将数据的状态更改为未修改，将数据的长度更改为零（用于挂起的显式回写），并执行隐式的回写。 另外，在每个显式回写之前，代理确定显式回写的地址和任何进入的窥探请求请求是否相同。 如果存在匹配，代理将在显式回写之前将显式回写的数据长度更改为零。
